Fighting with environment variables via SSH on an Ubuntu server? You’re definitely not alone there. Normally when running ssh <server> <command> the user’s ~/.bashrc should be sourced (if the user has Bash as shell) but for some reason, none of my variables got loaded.

After quite some googling, I found this post that described the same problem I had but also contained a simple solution in the comments section: Actually reading the .bashrc ;-) Ubuntu’s default .bashrc starts with following line:

[ -z "$PS1" ] && return

The problem is now, that this condition is actually true via ssh <command>. To solve this you have more or less 2 options: Add you stuff before this line or remove this line.
